question 41

Multiple Choice

For the reaction PCl₃(g) + Cl₂(g) PCl₅(g) at a particular temperature,K_c = 32.4.Suppose a system at that temperature is prepared with [PCl₅] = 0.50 M,[Cl₂] = 0.4 M,and [PCl₃] = 0.10M.Which of the following is correct?

• A)The system will proceed in the direction of forming more PCl₅ and Cl₂ until equilibrium is reached.
• B)The system is at equilibrium.
• C)The system will proceed in the direction of forming more PCl₅ until equilibrium is reached.
• D)The system will proceed in the direction of forming more PCl₃ and Cl₂ until equilibrium is reached.
• E)The system will proceed in the direction of forming more PCl₃ and PCl₅ until equilibrium is reached.
